Causes and treatments of yellow leaves of Cordyceps sinensis

1. Lighting issues

Reason: Cordyceps is light-loving and needs to be grown in an environment with sufficient light. If it is not exposed to sunlight for a long time, its leaves will turn yellow, dry up and even fall off.

Measures: Move it to a ventilated place with certain scattered light to ensure that it receives certain light every day. However, when the light is too strong in summer, you need to avoid strong light and take shade measures.

2. Too much water

Reason: If you water the cordyline too much, the moisture in the soil will increase, causing the roots to be unable to breathe normally and even rot, and the yellow leaf problem will follow.

Measures: If there is too much water, you need to stop watering immediately, loosen the soil, and wait for the water in the soil to evaporate in a ventilated place. If root rot occurs, remove the plant from the pot, remove the rotten roots, then change the soil and replant.

3. Unsuitable soil

Reason: It is best to use slightly acidic soil for the maintenance of Cordyline. If the soil is alkaline, it is not suitable for root growth and the leaves will gradually turn yellow.

Measures: The soil should be replaced immediately. Change to slightly acidic soil with certain fertility and good drainage. In subsequent maintenance, the soil needs to be changed every one or two years so that the soil conditions always meet its growth needs.

4. Temperature issues

Reason: The suitable growth temperature of Cordyline is between 18 and 25 degrees Celsius. If the temperature is too high, the leaves will turn yellow; if the temperature is too low and no insulation measures are taken, the plants will be frozen or even die.

Measures: If it is because the temperature is too high in summer, be sure to shade it. If it is a colder winter or early spring, it needs to be moved to a growing environment above 15 degrees.
